for eight or ten students. In this way each table can be made to accommodate twenty-two persons. These theaters are very comfortable and do not disturb the other work in the room.
In the two lateral angles of the room are constructed two cabinets for otorhinolaryngoscopy and for spectroscopy. The same cabinets can be used as dressing rooms for people, who undergo auscultation and registration of heart and respiration movements. It is in this place that apparatus is arranged for the survival of heart, intestines, etc. of mammalians. We have at our disposal two types of apparatus for heart-survival of cats, dogs, and rabbits. One is a rather large apparatus which is used for normal work where we obtain constant temperature, oxygen and pressure, the other where the whole apparatus can be sterilized. This apparatus is very useful for a prolonged perfusion and for studying the consumption of foodstuffs of living tissues.
Students’ Laboratory
The students’ laboratory is a room 12.50 meters deep by 15.80 meters wide, brilliantly lighted by three large windows on each of the two opposite sides. The room has in the middle two large tables 10 meters long and 1.60 meters wide; in front of the windows and along
the walls are additional tables, so that we have a table length of 75 meters available for practical student work. All the tables are fitted with lockers and drawers as well as with water, gas, and electricity. Cupboards for the instruments, pictures on the wall explaining the most usual experiments, a large blackboard, and some fume cupboards complete the furnishing of the room.
The two tables in the middle are provided with shafting driven by an electromotor, and fitted with stepped pullies, so that a great number of students can work at the same moment with kymographs. We can put at their disposal for all kinds of electric work an accumulator of 2 volts, the direct current of 120 volts, and alternating current of 125 volts. In the middle of the tables there are two central points for distributing the different currents.
The practical course of experimental physiology is so arranged that two students are always working together. They find on a determined place a picture with a description of the enumerated experiments, and further all the apparatus and supplies necessary. Every student has a card on which is written the date and number of the experiment, following a certain program. He is not allowed to advance to another experiment without receiving upon his card the
